Abstract: In this paper, the optimal bandwidth scheduling problem for UWB networks was formulated as a utility maximization problem Concerning the system bandwidth allocation, utility function is an effective measure of QoS. Utility reflects the user's satisfaction level to the assigned resource. Due to the complex coordination among users and links of wireless UWB systems, we proposed the problem with a decentralized scheme, which adapted naturally to changing wireless network conditions. We allocated system bandwidth based on utility, which fulfilled high rate transmission of UWB systems.
